Total allocation count?

turn GC off, you should look at my instrumented GC VM work and the  
change set that lets you look at the GC numbers on each GC.

To turn GC off you could make new space very large, and set the  
object allocation limit very high and the new space gc boundaries  
high, then it will allocate objects and do
no GC work until you run out of memory.

You can get signalled on each IGC so you could collect the object  
allocation count at that time.
